Configuring the Solid State Disk

The system supports two external Solid State Disks (SSDs) for customer data, logging and VNF data. These two SSDs work independently.

You can configure the Solid State Disk (SSD) on the device for local persistent storage.

To initialize and add an SSD:

Platform-Specific SSD Behavior

Table 1: Platform-Specific Behavior

NFX350

Difference

SSD vendor recommendation

Third‑party external SSDs are not recommended

Power state for SSD insertion

Device must be powered off

CLI command for manual initialization

request vmhost storage external-disk-1 initialize [force]

Automatic initialization condition

SSD present during USB install, clean install, or zeroize

SSD binding behavior

SSD is tied to the device after initialization
  1. Log in to the JCP CLI and enter configuration mode:
  2. Initialize an SSD:

    There are two slots for SSD, slot 0 and slot 1. The disk name should be either public-disk0 or public-disk1 based on the SSD slot.

    Note:

    You can store VNF images in the /var/public-disk1 folder.
  3. Add an SSD:
  4. Verify whether the SSD is added:

    In the output message, /var/public shows details of the internal SSD and /var/public-disk1 shows details of the external SSD that is plugged in slot1.

  5. (Optional) Re-initialize the SSD:
    Note:

    Upgrade using USB re-initializes and adds the external SSD.

To remove the SSD:

  1. Remove the SSD:

  2. Power off the device.

  3. Remove the SSD.

Note:

SSD is not formatted when you remove it. To erase the data before removing the SSD, re-initialize the SSD.

Hot-swap of external SSDs is not supported-Removing an external SSD while the device is powered on may lead to unpredictable or unsupported software behavior.

If the VNF configuration references the public disk path, removal of the SSD is strictly prohibited. Doing so may impact system stability and functionality.
